A thermocouple with a sensitivity of 0.0225 mV/F is used to measure temperature. The signal from the thermocouple is passed through a non-inverting amplifier as below. Where the resistors R, = 9.99k and R₁ =1002. The amplified signal is then passed through an 8 bit A/D converter. If the the full scale voltage is 10V. a. What is the temperature resolution? b. What is the range of temperature can be measured from zero? c. If measuring a temperature of 200° F, what is the voltage indicated by the A/D converter? What is the reading of temperature from the DAQ system? ww Op-amp m
Power Amplifier
The power amplifier is an electronic amplifier designed to maximize the signal strength of a given input. The input signal strength is enhanced to a high enough level to drive output devices such as speakers, headphones, RF (Radio frequency) transmitters, etc. Unlike voltage / current amplifiers, the power amplifier is designed to drive core loads directly and is used as a storage block in the amplifier series.
Maximum Efficiency Criterion
In every field of engineering, there is a tremendous use of the machine and all those machines are equipped for their popular work efficiency so it very much important for operation engineers to monitor the efficiency of the machine, planning engineers to check out the efficiency of the machine before installing the machine and design engineers to design machine for higher efficiency than and then the utility will procure their products that will ultimately lead to profit and loss of the company. It indicates the importance of efficiency right from the initial stage as manufacturing units, intermediate stage as planning coordinators, and end-users stage as a utility.
